The inherited cardiomyopathies comprise a group of genetically heterogeneous diseases, the most common of which are hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), arrhythmogenic right ventricular cardiomyopathy (ARVC), and left ventricular non-compaction (LVNC).  These disorders have an impact across all age groups.  Overall, the prevalence of these disorders is estimated at approximately 1/500 (0.2%). 

LVNC is a type cardiomyopathy defined hypertrophic left ventricle with deep intertrabecular recesses and poor systolic function (left ventricular dilation may or may not be present). This next-generation sequencing test is designed to detect mutations in the coding region of 12 genes associated with Non-Compaction Arrhythmogenic Left Ventricular Cardiomyopathy.

Reasons for Referral:

  • Echocardiogram results suspicious for cardiomyopathy.
  • Clinical presentation consistent with left ventricular non-compaction.
  • Positive family history for left ventricular non-compaction (targeted testing is available if familial mutation is known).
  • Carrier testing.

For detailed information and ordering instructions, please refer to Full Gene Analysis (1240). Genes may be added or removed from the list below if clinically indicated.

Non-Compaction Arrhythmogenic Left Ventricular Cardiomyopathy (12 genes): ACTC1, ACTN2, DTNA, LDB3, LMNA, MYBPC3, MYH7, MYL3, TAZ, TNNT2, TPM1, VCL

Additional Info:

The Knight Cancer Institute at Oregon Health & Science University is a pioneer in the field of precision cancer medicine. The institute's director, Brian Druker, M.D., helped prove it was possible to shut down just the cells that enable cancer to grow. This breakthrough has made once-fatal forms of the disease manageable and transformed how cancer is treated. The OHSU Knight Cancer Institute is the only National Cancer Institute-designated Cancer Center between Sacramento and Seattle – an honor earned only by the nation's top cancer centers. It is headquarters for one of the National Cancer Institute's largest research collaboratives, SWOG, in addition to offering the latest treatments and technologies as well as hundreds of research studies and clinical trials.
